Our Spring issue takes you behind the curtain for our Marimba Swarm sessions plus multi award-winning composer / producer Simon Franglen gives us a tour of his studio. We also take an up close look at the French Horn and an in depth look at our own eDNA library. The agents of Cool Music tell us what they do, and Spitfire's own Christian Henson gives us some tips on how to make sampled strings "sparkle."
